 Change the **default list** of substitute servers by starting `guix-daemon` with
 the `--substitute-urls` option (you will likely need to edit your init script):
 
 ```sh
-guix-daemon <cmd> --substitute-urls='https://guix.carldong.io https://ci.guix.gnu.org'

 ```
 
 Override the default list of substitute servers by passing the
 `--substitute-urls` option for invocations of `guix` commands:
 
 ```sh
-guix <cmd> --substitute-urls='https://guix.carldong.io https://ci.guix.gnu.org'

 ```
 
 For scripts under `./contrib/guix`, set the `SUBSTITUTE_URLS` environment
 variable:
 
 ```sh
-export SUBSTITUTE_URLS='https://guix.carldong.io https://ci.guix.gnu.org'
